2 SHEETS-SHEET 1.

WITNESSES mmvron 6% 7M 4 A TTOR/VEYS from the pipe 22 extends into the interior or chambered portion of the top. Each of the branches 26 of the pipe22 is provided with cross or transverse pipes 27-at spaced intervals, and at each discharge nipple 25 each of the transverse pipes 23 is provided with a downwardly extending discharge tube or nipple 28.

It will be evident that when a glass is arranged on the tray over a discharge tube 25, it will be beneath a discharge tube 28 of the pipe 22, and the pipe 22 leads from the boiler below the water level, so that the nipples or tubes 28 discharge water onto the glasses. A hood 29-is'provided for each article, the hood fitting the bottom or lower end of the glass, and each hood is provided with a reduced portion 30, which extends through an opening in a plate 31. With each plate 31 there is connected a hood 29 for each article, and each hood and reduced portion 30 is provided with an opening 32 extending from the upper end of the reduced portion to the interior of the hood.

The opening 32 of each hood is engaged by the adjacent discharge tube or nipple of the water supply pipe, and the said tubes or nipples fit loose enough in the openingsto permit the plates 31 to be raised and lowered.- The plates 31 are spaced apart from eachother at regular intervals, and each plate is connected to the next upper plate by means of tour flexible members 33, the said members being of cord or wire.

The uppermost plate 31 has connected with each corner a flexible member 33, similar to the members 33, and the said flexible members pass upwardly over pulleys 34 journaled at the top of the casing, and outwardly to a connection at 35 with the adjacent door 3. The arrangementis such that when the door is opened, all of the plates andall of the hoods will be simultaneously lifted, as indicated in Fig. 1, while when the door is closed all of the plates 31 and the hoods 29 will be lowered.

The trays 14 may be removed, since the trays are not connected in any manner to the partitions 12 or to the bottom 12*, or to the discharge tubes 25. Each tray is provided with openings fo receiving the said tubes 25,.so that the tray may be seat- .ed on the partition or on the bottom, the discharge tube passing upward through the opening. In that part of the compartment 2* below the partition 11, guides 36 are provided, for receiving the trays 14.

T he operation of the device is as follows: The glasses to be washed and sterilized may be first properly placed on the trays, each glass being placed over an opening. The

trays are then placed in thecompartm'ent 2,

with the discharge tubes 25 passing upwardly through the openings of the tray, as

shown in ,Fig. 2, When the door-3 is closed,

the hoods will be lowered onto the glasses, and the sterilizer is now ready for operation. The steam generated in the boiler passes throughthe pipe 22, and is discharged through the tubes 25 into the interior of the glasses, thoroughly cleansing and sterilizing the same. The boiling water passes out from the pipe 22 and is discharged from the pipes 28 on to the glasses, striking the bottoms first, and then running down the sides of the glasses. After the glasses have been thoroughly cleansed, they may be removed in the trays from the compartment 2, and inserted in the compartment 2, the trays resting on the guides 36.

With a sterilizer of the size shown, fortyeight glasses may be simultaneously washed and sterilized. lltwill be obvious, however, that the number of articles sterilized at one time will depend upon the size of the sterilizer. It will be noted from an inspection of Fig. 2, that the top of the casing at the compartment 2 is provided with an opening 37 leading into the hood 9, and the chambered top 12 oi? the casing is pro vided with a similar opening 38 at the hood,

both walls of the said top being perforated.-

The extension 7 of the conduit 13 also opens into the hood. Thus all of the waste steam and the products of combustion from the,

heater may pass out at the hood.

The extension 8 at the bottom. of the con duit permitsthe air to enter to provide for a circulation of air through the conduit, to rerpove the products of combustion and the waste steam. The gage 20 always indicates the pressure in the boiler, and the water gage indicates/the height of water. It will be noticed that the pipe 19 opens above the water level while the pipe 19 opens below the same.

In use, the glasses are first thoroughly cleansed by the boiling water,.discharging through the pipes 26 and 28, thus thorough ly cleansing the glasses. After they have been thoroughly cleansed they may be sterilized by the steam and the hoods 29-30 protect the glasses against breakage.

Suitable valves 40 and 41 are provided for regulating the flow of water and steam from the boiler to the articles, the former being placed in the hot water pipe 22 and the latter in the steam pipe 22. The val e. 40 is for the purpose of admitting and shu F' ting or? the flow of waterto the brhnch'.

pipes 26, while the valve 41 is for the purpose of controlling the flow of steafn from the boiler to the discharge nozzles 25. The

boiler is provided with the usual filling opening 42, for the purpose of permitting the same to be filled with water.
